ILLINOIS, ASSIGNOR, BY MESIl'E ASSIGNMENTS, TO THE KINGfiL'EY-MILLEBCOMPANY, OF CHICAGO, ILLINOIS, A CORPORATION COMBINATION RADIATOR CAPAND MOTOMETER HOLDER.

Application filed April 18, 1921. Serial No. 462,271.

My invention relates generally to radiators tor automobiles, and moreparticularly to caps for the radiator inlets audit consists in thecombination, constructions and arrange ments herein described andclaimed. p y d An object ct my invention is to provide a radiator capthat is adapted to be locked in adjusted position on the inlet oil" aradiator.

A further object of my invention is to provide a device of: thecharacter described that is adapted for engagement with a temperatureresponsive mechanism eter type, whereby the latter is maintained in adesired cannot be displaced. r adily.

A further object of my invention is to provide a radiator cap that isadapted to be moved instantly into either closed or open position withrespect to the inlet of a radiator and is provided with means formaintaining the cap norinally in closed position.

A. :turther object oi my invention is to provide a device of thecharacter described that can be applied to a radiator of an ordinaryconstruction without any extensive change ii any, being required in theusual construction or the latter.

A -hn'ther object of my invention. is to provide device oi the characterdescribed that is thoroughly elilective tor the purpose intended andpractical con'nnercially.

()ther obje is and advantages will appear in the iolldwnurspecitication, and the novel iisaiturcs: oi the invention will beparticular- '1' ly oiuted out in the appended claims.

' i Y invmi tiou is illimtrated in the accomo drawings forming part ofthis up jglic on in which l i c no 1 a central vertical section throughthe device. showing the use and application thereof,

llinure 2 is a trapjmentary portion ot a inotoineter ported. therebybeing .niown, and

Figure 3 is a top plan view oi? the device, showing alid portion thereoi1n open position. 7

Referring now to the drawings, 1 denotes portion oil. a radiator havinga tubular inlet 2 threaded interiorly at 3. A radiator cap e1nbodying myinvention compr ses a tubular body portion a having an enteriorlythreaded reduced stem portion Supot the Inotomi position on the cap andsine elevation of the device,

ing; 25 through the 5 adapted to be screwed into the interiorly threadedinlet2. The

body portion t is formed with an interiorly extending annular lll) 6 andwith an upstanding annular shoulder 7 intermediate its inner and outerwalls, thereby defining an inner socket S and an outer socket 9 that isconcentric with the inner socket 8.

A lid or cover portion 10 of the cap is formed with an inwardlyextending annular flange 11 at its lower end adapted to overlie theupstanding shoulder 7 and defining a depending annular shoulder 12 thatis adapted to the outer socket 9, as best seen inFigure l. The cover 1 0has a pair of spaced apart in tegral lugs lit-+13 extending laterallythereof and arranged to straddle a cooperating lateral lug 14: that isintegral with the body portion 4. j The lugs lid-13 are fixedly securedto the lug lt by a pintle 15 so that the cover 10 may be swung about thepintle 15 into open position, as illustrated in Figure 3. The ends ofthe pintle 15 are upset so that the cover 10 cannot be detached from thebody portion 4: without the use oi great force or heavy tools.Oppositely extending handle members 16--l6 are provided as a convenientmeans for moving the cover 10 with respect to the body portion a. Thebody portion 4 is formed with an integral. extension 17 that is reducedat 18 and is diametrically opposed to the lug l l. A. latch 19, which issubstantially U-shaped, has the arms thereof arranged to straddle a log20. The arms oi the Ushaped latch are secured to the lug 2O bya pin 21or the like so tlutt the latch may be swung into engagement with thereduced portion 18 of the lug extension 17 and the web of the latch willfrictionally engage with the reduced portion 18 to normally maintain thecover 10 in closed position with respect to the body portion l, as bestseen in Figure 2.

The body portion t is locked in adjusted position with respect to theradiator inlet 2 by means of a key 22 that is projected into alinedlreyways 28 and 24: in the contiguous walls of the stem portion 5 andthetubular in let 2. The keyway 24 continues into an openbody portion t sothat the key 24 may be driven into place from the interior of thelatter.

From the foregoing description of the various parts of the demos, theoperation thereof may be readily understood. It is frethe inlet of a1'adiator,'a cover for said ture responsive plied.

Themotometei 26 has a threaded shank 27 screwed into a threaded opening 28in the cover so that a ange 29 rests upon the cover. The shank 27depends below the cover 10 into the interior of the bodyportion. A lookwasher 30 and a nut 31 placed on the threaded shank 27 tends to maintainthe motometer in place. It been found in service that the vibration ofthe vehicle to which the device is-applied will cause the nut 31 to bedisplaced and the Fmotometers are frequently lost. Furthermore, the lossof the motometers is frequently due to theft, since the nut'31 may bereadily removed. In order to prevent the loss of the motometer, Iprovidea substantially dish shaped spring member 32 that has an inwardlyoffset portion 33 and an outwardly extending flange 34 at its upper end.The spring member 32 is formed with a central opening 35"adapted toreceive the end portion It is obvious that when the is applied to thecover 10 same into the position illusso that the flange 34 overof theshoulder 11 and the presses outwardly against the annular rib 11 thatthe be readily removed-from the interior of the cover 10 andconsequently removal of the nut 31 from the shank 27 is precluded.

One of the principal advantages of the device is derived from thefactthat the cover 10 position instantly to permit the filling of theradiator 1 in an ordinary manner and that the cover 10 is normallmaintained in closed position by the latching dicating the t h yspringing the lies the upper wall the inner wall of I claim: V
